Operating principle of an armored door lock

To be able to change the lock on your armored door , it is important to know how it works. A lock comprises a box which is composed of handles, a bolt, a cylinder and a rod. The cylinder is the component in which the key is inserted and in which the bit is activated. Activating the bit drives the deadbolt and closing points. These are stuck in the strikers. Note that these strikes are found at the door jamb.

The locking of the lock is ensured by the bolt and the rollers which are fixed in the strikers. The latchbolt, on the other hand, is the mechanism that allows the door to open instantly when you turn or lower the handle. The latter works without the use of the key.
